SMART^(R)/ASTC技术在连铸冶金操作和经济诸方面的效益

Metallurgical, operational and economic benefits of SMART^(R) /ASTC technology in continuous casting

与SMART^(R)扇形段技术配合使用的自动控制铸坯锥度(ASTC)的发展和应用,减少了中心偏析,使铸坯内部质量得到明显改进。遥控调整辊缝锥度和动态轻压下的应用,也能满足瞬间浇铸条件的特殊要求。到2003年5月止,在芬兰、美国、意大利、奥地利、韩国和中国共有9台11流板坯连铸机使用SMART^(R)/ASTC技术进行操作。另外,还有7台18流其它类型的连铸也已订购采用这项技术。SMART^(R)/ASTC技术对于在板坯和大方坯连铸机上浇铸所有的钢种都很理想。在大方坯连铸机上应用的实例是计划安装在中国攀枝花钢铁集团的6流大方坯连铸机。

The development and implementation of automatic strand taper control (ASTC) used in combination with SMART^(R) segment technology leads to considerable improvements in the internal strandquality of continuously cast steel through the reduction of center segregation. The roll-gap taper isremotely adjusted and with the application of dynamic soft reduction the special demands for transientcasting conditions can also met. As of May 2003 nine slab casters comprised of a total of eleven strands are operating with SMART^(R)/ASTC technology in Finland, USA, ltaly, Austria, Korea and China. Additional orders have been placedfor the installation of this technology in seven other casters having a total of eighteen strands. SMART^(R)/ASTC technology is ideal for the casting of all steel grades in both slab and bloom casters--the latterexemplified by the scheduled start-up of the six-strand bloom caster at PANZHIHUA Iron & SteelGroup in China.
